SUSPENSION DEVICE FOR VEHICLES.

Application. filed April 2 1927, Serial No. 187,064, and in France May 6, 1926.

The present invention relates to a suspension device for vehicles in which the rear springs are no longer situated adjacent the wheels, but are disposed in the interior of the vehicle frame and are supported at one end by the cross-pieces of the frame and at the other end by the thrust tube of the rear axle.

In this arrangement the springs are concealed in the interior of the vehicle body and will hence offer no resistance to the forward travel, and this is chieflyadvantageous for high-speed vehicles with tapered bodies.

Further, the support by which the springs are mounted on the said thrust tube is so disposed that the tube and the support are rotatable on one another; this will much reduce the reaction of the oscillations of the rear wheels about the axis of the vehicle and hence the displacements of the vehicle body will be diminished.

In this manner the rear wheels are made practically independent as to their relation to the vehicle body.

The appended drawing shows by way of example an embodiment of the invention.

Fig. 1 is a lengthwise section of the vehicle,

Fig. 2 is a corresponding plan View, and,

Fig. 3 a rear view.

1 is the vehicle body comprising the crosspieces 2 and 8 upon which are mounted the shackles 4t and 5 o l. the springs 6 which are secured by the straps 7 or by like means to r the support 8 which is rotatable on the thrust tube 9.

The support 8 comprises a two-part collar which is held by the bolts 10-with the interposition of springs l1-so as, to press the said support upon the tube in an elastic manner, whereby the angular oscillations will be damped.

In the present apparatus, the lengthwise motion of the support 8 relatively to the tube 5) is prevented by the thrust rings 12 secured to the said tube.

lt is obvious that Without departing from the principle of the invention, it is feasible to dispose a single suspension spring in the vertical plane passing through the axis of the said thrust tube. The longitudinal position of the spring or springs may be varied. The springs might be placed in the transverse position or otherwise according to any suitable inclination, provided they may be disposed between the main side bars of the frame.

Having thus described my apparatus, what I claim as new therein, and my own invention, is

In a suspension device for motor vehicles provided wit-h a vehicle frame comprising vehicle frame and also with the said tube.

In testimony whereof I have hereunto affixed my signature.

CHARLES SCHAEFFER.
